Analysis of Developments in Plant Production in the Governorates of the Asir Region, Saudi Arabia

Abstract

Plant production is diverse in the Asir region, and there are many methods of analysis. Perhaps factor analysis is one of the most important statistical methods through which productive power can be measured in various geographical regions. In this study, factor analysis was used to measure the developments of plant production in the agricultural sector in the Asir region, Saudi Arabia. The factor analysis showed the presence of three main factors that together explained about %86.55 of the total variation in the development of plant production in the governorates of the Asir region. The study showed three mathematical algorithms that can measure the development of plant production in the Asir region according to the three main factors:  

First factor equation                                                                                                                                                                                                       

λ1=44.250%=-0.521*X_1 0.810*X_2+0.78*X_3+0.842*X_4+0.755*X_5

Second factor equation

λ2=24.960%-0.228*X_1+0.352*X_2+0.936*X_3-0.226*X_4-0.380*X_5

The third factor equation

λ3=17.344%0.796*X_1+0.291*X_2+0.104*X_3+0.339*X_4-0.153*X_5

-The study classified the governorates of the Asir region, based on the results of the analysis, into three groups, according to negative and positive  0.933-0.975 and includes Bisha - Abha - Ahad Rafaida - Khamis Mushait - in Al-Furn - Al-Barak, while the second group represents the category of  0.897-0.548  and includes the governorates of Mahayel, Asir - Tanmomah - Al-Namas - Tathleeth. The third group includes the category of 0.255--0234 and includes the governorates Sarat Ubaidah - Al-Majadra and Bariq - Tareeb - Dhahran Al-Janoub and Al-Harajah - Rijal Almaa
